✦ Synopsis
The quantum yields of the c&+tm,ls and fnms+cis Hg 6(3P1) photosensitized isomerizations of butene-2 are both 0.50 + 0.02 for butene2pressures > 30 torr. The formation of excited mercury-butene-2 complexes, invoked by Tsunashima and Sato to explain an apparent loss of incident photons, does not occur. The quantum yields determined by Yang for hydrogen formation in the Hg 6(3P1) photosensitization of ethylene seem to be in error.

The photolysis of SOz at 3712 A in the presence of the 1,2-dichloroethylenes has been investigated at 22°C. The data are consistent with the SOz( 3B1) photosensitized isomerization of the 1,2-dichloroethylene isomer. A kinetic treatment of the initial quantum yield data was consistent with the forma
